I would advice you to think twice about it, before you start coding. :-)

Talking only about our code, IMDbPY is released under the GPL 2 or
later license.  This means that every IMDbPY-based program MUST be
released under GPL 2 (or later) or any GPL-compatible license [1].

But your real problem is not the code, it's the data that code
works on.
These data are owned by the Internet Movie Database company (see
our disclaimer [2]) and getting a license for a non-personal
usage will cost you no less than 15.000 USD (the last time I
checked, at least).  Moreover, I assume that your application will
access their server (through IMDbPY), and this would probably not
be tolerated, from a commercial application.
_Maybe_ they would accept it if your application is free (gratis) _and_
if it uses only the plain text data files (but this is just _my_
guess - their legal department is entitled to a different opinion ;),
but I don't think this is what you want.

Last but not least, I have more than serious doubts that such an
application could be accepted by Apple itself: they canned programs
from the iPhone Store for much less "controversies". :-/

You can use IMDbPY for free (in the "no money" sense) _and_ your
program MUST be free (in the "free software"/"open source" sense) and
released under one of the above mentioned licenses.

As stated above, at the same time you have to respect the IMDb's
terms of service (and this is the tricky part... ;-)

I'm not sure about what you're meaning here: IMDbPY accesses its
data from two sources: the IMDb's web server itself, and/or a local
copy of the plain text data files distributed by IMDb [3].
IMDbPY is not affected in any way by the operativity of sourceforge.net,
and we can easily move the development elsewhere, in case of need.

To summarize: using IMDbPY you have to respect _both_ its license
and the license of the IMDb's data.  These two conditions reduce
your options to a free software written and used only for personal
and non-commercial usages.


Hope this helps.
